(36:7) Thy righteousness is like the mighty mountains; Thy judgments are like the great deep; man and beast Thou preservest, O LORD.- Jewish Publication Society Bible

Wesley's Notes for Psalms 36:6

36:6 Mountains - Stedfast and unmoveable: eminent and conspicuous to all men. Judgments - The executions of thy counsels. Deep - Unsearchable, as the ocean. Man - The worst of men; yea, the brute - beasts have experience of thy care and kindness.
